REFRIGERATING CABINET.

Application filed November 11, 1827. Serial No. 232,559.

My invention relates' to ice cream containers. The invention herein disclosed has for an object t0 provide a cabinet and receptacies so disposed therein as to lend-itself to the keeping of ice cream which requires the maintenance of a relatively low temperature.

An object of the present invention is to provide against undue cooling of thecontents of the ice cream cans near the bottom portions thereof, in excess of the cooling had in the upper portions of the cans, which are.v from time to ti'me, during dispensing periods, exposed to the temperatures existing outside of the cabinet in which the cans are placed.

An object of my invention also is to provide 'for the accomplishing of the aforesaid object in a cabinet such as that employed in connection with soda fountains wherein a number of icecream cans may be received.

A nother object of my invention is to attain the aforesaid and other objects in a construction whereby possible cont-act between the brineand cork or other heat insulating materials is avoided.

Another object of my invention is to provide a construction adaptable for the ready removal for purposes of inspection and repair of the receptacles contained within the cabinet, and adapted for the reception of ice cream cans. p

Other objects of my invention and the in vention itself will become apparent by reference to the following description of` an embodiment of my invention and in which description reference will be had' to the accompanying drawings illustrating the said embodiment.

In the drawings:

Fig. 1 illustrates in longitudinal medial section an embodiment of my invention.

Fig. 2V illustrates a transverse section taken on the line 2-2 of Fig. l. y

Fig. 3 is a fragment in longitudinal medial section of a bottom end portion of a receptacle which is a modification of those shown in the foregoing figures.

Referring now to the drawings in all of which like parts are designated by like reference characters, at 1 I show an outer casing for the cabinet, preferably of sheet iro-n or steel with its outer surface enameled with porcelain, glass or the like to prevent corrosion and to enhance its appearance, vand preferably supported on adjustable feet 2 disposed below the four corners of the casing. The casing is supported internally by an angle iron frame work comprising frame elements 3, 4, 5, 6y and 7 together with wood frame elements 8 and 9.

Within'the casing 1 I provide a lining 10 of cork or other suitable heat insulating material v of substantial thickness. As illustrated, the outer casing 1 is of substantial rectangular form. Within the cork lining 10 there is telescoped a rectangular tank 11 which fits closely within the cork lining and which terminates at itsupper end in an outwardl extending iange 12. The tank 11 is prefera ly made of sheet copper or other metallic material which is not subject to corrosion when exposed to brineand like liquids `employed'as a refrigerant medium within the tank. The

Vcopper tank is packed tightly in place by the cork lining 10 which may b'e inserted in sections in place.

At 13, I show a plurality of ice cream can p receiving containers which are adapted for the reception of ice cream cans 16 indicated by dotted lines in the drawings. The receptacles are of sufficient transverse dimensions that the ice cream cans 16 may be placed therein, and in the ,embodiment illustrated two cans in each receptacle, so as to be easilyV top plate borders being received withinV grooved' recesses of the wood frame members comprising the members 8 and 9. A superstructure is then provided comprising a metallic casing 23 -having openings '24 through which receptacles 16 may be passed, the casing 23 being filled with wood fillers 21 and cork fillers 22 or other fillers of suitable heat insulating material.

Hollow metallic covers 25 filled With cork or like material and provided with handles 26 rest by their lateral fianges 27 upon the superstructure 22 and project by depending portions 28 within the openings 24 of the superstructure. The ice cream cans are of such diameters as to readily pass through the openings 24. Each of4 the receptaclesm13 preferably have rounded end walls 14 and straight side walls 15 so as to accommodate a plurality of ice cream cans, two being vaccommodated in the receptacles herein shown,

with a minimum of space between the exterior surfaces of the cans and the walls of the receptacle.

For each of the receptacles is provided an ,insulating boot 29 comprising an outer enclosing wall 3() and a bottom wall 31 which is secured to inturned portions of the wall 30 at 32 such as by soldering. yThe boot'has insulatedl lining 33 and terminates at its upper end in a short vertical portion 34 preferably soldered to the exterior' surfaces of the receptacle, making a tight joint with the re- I ceptacle 13. Sometimes as illustrated in Fig.

3, which illustrates a'fragmental view of a lower end portion of a receptacle 13 in longitudinal medial section such as that of Fig. 1, I may only provide a collar or sleeve portion such as 29 of the boot,'omitting any insulating boot portion such as that shown at 35 Fig. 1, below the receptacle. In such a case the lower harder portions 36 of the receptacle make close contact with the bottom wall of the tank 11 and prevent any circulation of brine below the bottom walls 38 of the receptacles.

The outer casing 30 for the boot 29 is preferably made of copper or like material which is not subject to corrosion by brine or other refrigerant, which is placed in all of the i spaces indicated by the reference numeral 37 within the tank 11 and without the recep-l t-acles 13 cooling of the brine may be effected by the well known action of a refrigerant boiler 39 and tubes 40, of any of the well known types, and which boiler and tubes are supported in the space 37ipreferably`intervmediate two of'the receptacles 13 as illustrated. When the boiler and coils areA dis posed in the cabinet tank closely adjacent one of the receptacles such as the intermediate one illustrated in the drawings an insulating wall 41 of m-etallically enclosed cork or other heat insulating-material may extend transversely of the tank, therein, and intermediate the boiler and coils and such intermediate receptacle to thermally shield the intermediate receptacle from excessive refrigerant effect due to close proximity to the boiler and coils. Suitable openings 42 and 43, indicated by dotted lines in the drawings, per- 'other constructions isoften the case. the boots being made integrally with the mit circulation of bring through the wall 41 4in portions of -said wall relatively remote `from the boiler and coils.

Due to the insulating boots nonremovably carried by the-bottom portions of the receptacles, the ice cream cans contained therein will receive less refrigerating effect in their bottom portions than would otherwise be the case, so that the ice cream will not be unduly hard in the bottom portions of the cans as in Also receptacle removing the receptacles and boots as a unit for cleaning, inspection, or repairs as the case may be, is made possible. Also in this construction no reliance whatever is placed upon pitch or the like to prevent access ot' brine to the cork, or other heat insulating materials employed, and which are subject to deterioration, creating objectionable odors when brought in contact with brine It is found undesirable to rcly on pitch or the like to effect a seal against brine since in some compositions of pitch, the pitch itself is subject to attack by brine and in any event fractures of the pitch seal sometimes exist due to handling of the cabinets in shipment or in moving from one position to another orA by the ordinary use in placing ice cream cans in and removing them from the receptacles.

Having thus described my invention as a specific embodiment, I am aware that numerous and extensive departures may be made from thc embodiment herein described but without departing from the spirit of my invention.

I claim:

1. In a refrigerating cabinet, the combination with an outer-casing, a tank telescoped n therein, a heat insulating lining interposed between the tank and the casing, an ice cream can receptacle within the tank and a heat insulating boot rigidly secured to only the lower end of the receptacle, said receptacle with said boot being removable as a unit from the tank, said boot thermally shields the walls of the receptacle from the maximum chilling effect of brine contained within the tank exteriorly of the receptacle.

A 2. In a receptacleadapted for insertion in a refrigerating cabinet and adapted to receive icecream cans telescoped within it, an insu lating boot for the lower end of the receptacle comprising a metallic outer wall and a heat Y insulating lining within the wall, said .wall being metallically secured to the outer surface of the receptacle so as to hermetically enclose the heat insulating material between the receptacle and boot walls.

3. In a refrigerating cabinet the combination with a tank, a plurality of receptacles adapted to be telescoped therein each adapted to receive at least one ice cream can, each receptacle comprising an insulating collar rigidly affixed to the outer surface of its 1ateral walls, said collar and receptacle being removable from the tank as a unit.

4. In a refrigerating cabinet the combination with a tank, a plurality of receptacles adapted to be telescoped therein each adapted to receive at least one ice cream can, each receptacle comprising an insulating collar rigidly aiiixed to the outer surface of its lateral Walls, said collar and receptacle being removable from the tank as a unit, said collar comprising an outer metallic wall'and an inner lining of heat insulating material, the outer Wall being joined to the lateral Walls ot' the receptacle so as to provide a hermetic fluid-tight seal therewith to exclude brine or other refrigerant content in the tank exteriorly of the receptacle from contact with the heat insulating material of the collar.

5. In a refrigerating cabinet the combination with a tankya plurality of receptacles adapted to be telescoped therein each adapted to receive at least one ice cream can, each receptacle comprising an insulating boot rigidly aflixed to the outer surface of its lateral and bottom walls, said boot and receptacle being removable from the tank as a unit, said boot comprising an outer metallic Wall andan inner lining of heat insulating material, the outer Wall being joined to the lateral and bottom Walls of the receptacle so as to provide a hermetic luid-tight seal therewith to exclude brine or other refrigerant content in the tank exteriorly of the receptacle from contact with the heat insulating material of the boot.

In testimony whereof I hereunto aliix my signature this 27th day of October, 1927.
